This patch updates the vmkusb VIB to resolve the following issues:
The ESXi host might fail with a purple screen when booting the ESXi host on the following Oracle servers: X6-2, X5-2, and X4-2, and the backtrace shows that is caused by pcidrv_alloc_resource failure. The issue is caused because the system cannot recognize or reserve resources for the USB device.
When a Keyboard is configured with a different layout other than the U.S. default, and later it is unplugged and plugged again to the ESXi host, the newly-connected keyboard is assigned with U.S. default layout instead of the user-selected layout.
On some servers, a USB network device is integrated in IMM or iLO to manange the server. When you reboot IMM by using the vSphere Web Client or an IMM or iLO command, the transaction on the USB network device is lost.
The XHCI related platform error messages, such as xHCI Host Controller USB 2.0 Control Transfer may cause IN Data to be dropped and xHCI controller Parity Error response bit set to avoid parity error on poison packet, are reported in ESXi VMkernel logs.
An ESXi host might become unresponsive with no heartbeat NMI state on AMD machines with OHCI USB Host Controllers.
ESXi hosts can be updated by manually downloading the patch ZIP file from the VMware download page and installing the VIB by using the esxcli software vib command. Additionally, the system can be updated using the image profile and the esxcli software profile command. For details, see the vSphere Command-Line Interface Concepts and Examples and the vSphere Upgrade Guide.
